Exploring the relationship between diabetes self-efficacy, depressive symptoms, and glycemic control among men and women with type 2 diabetes

Impact of depression on self-efficacy, illness perceptions and self-management among people with type 2 diabetes: A systematic review of longitudinal studies

BACKGROUND

Treating comorbid depression does not always improve outcomes for people with type 2 diabetes. Evidence is lacking on potential psychological and behavioural intermediaries of the impact of depression on diabetes outcomes.

OBJECTIVE

To synthesise evidence on the impact of comorbid depression on self-efficacy, illness perceptions, and self-management in people with type 2 diabetes.

DATA SOURCES

We searched PubMed, Embase, PsycINFO, and Global Health databases from inception up to 29th March 2023.

STUDY ELIGIBILITY CRITERIA

Only prospective studies (cohort or intervention studies) were included, with no restrictions on language. The outcomes were self-efficacy, illness perceptions, and self-management.

PARTICIPANTS

People with type 2 diabetes in community or health settings.

EXPOSURE

Comorbid depression or depressive symptoms in people with type 2 diabetes.

SYNTHESIS OF RESULTS

A narrative review of heterogeneous studies.

RISK OF BIAS

The risk of bias was assessed using the Effective Public Health Practice Project (EPHPP) quality assessment tool for quantitative studies.

RESULTS

Twenty-five studies were included, all from high-income countries. Depression was associated with lower self-efficacy (2 studies), poor illness perception (1 study), and poor self-management practices (17 studies) in people with type 2 diabetes. In 6/7 studies, depressive symptoms predicted less adherence to dietary recommendations, 8/10 studies found depressive symptoms were associated with poor medication adherence, 1/3 study found that depressive symptoms were associated with poor weight control, 3/4 with less physical exercise, and 2/3 with general self-care practices.

LIMITATIONS

There were no studies from low- and middle-income countries and non-Western settings, and we cannot assume the mechanisms linking comorbid depression with diabetes outcomes are similar.

CONCLUSIONS

Comorbid depression was associated with lower self-efficacy, poorer self-management, and less adaptive illness perceptions among people with diabetes.

Acculturation and glycaemic control in Arab immigrants with type 2 diabetes in Australia

AIMS/HYPOTHESIS

This study aimed to investigate acculturation's direct and mediated effects on HbA1c levels in individuals with type 2 diabetes from Arabic-speaking countries that are members of the Arab League who have emigrated to Australia.

METHODS

In this multicentre cross-sectional study, we recruited 382 Arabic-speaking immigrants who were born in any of the 22 countries of the Arab League and who had type 2 diabetes from different healthcare settings in Australia. HbA1c levels were retrieved from medical records. A validated self-report questionnaire was used to assess behavioural and psychosocial outcomes. Acculturation was measured using the General Acculturation Index and the Adherence to Traditional Values tool. We used structural equation modelling to test mediation hypotheses.

RESULTS

Participants had a mean HbA1c value of 63.9 mmol/mol (8.0%), a low acculturation level (mean±SD: 1.9±0.6; range: 1-5) and highly adhered to traditional values (mean General Acculturation Index value: 3.7±0.7; range: 1-5). Higher HbA1c was associated with lower acculturation levels (Pearson correlation coefficient [r] = -0.32, p<0.01) and higher adherence to traditional values (r=0.35, p<0.01). Self-efficacy, health literacy and self-care activities partially mediated the relationship between acculturation and HbA1c.

CONCLUSIONS/INTERPRETATION

Among Arab immigrants in Australia with type 2 diabetes, the degree of acculturation is related to glycaemic control, suggesting possible avenues for new interventions.

Sex differences in symptom network structure of depression, anxiety, and self-efficacy among people with diabetes: a network analysis

Aims

The present study aims to explore the relations between symptoms of depression and anxiety and self-efficacy among people with diabetes. At the same time, we also examined the sex difference between network structures.

Methods

This study recruited 413 participants with diabetes, and they completed Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire (PHQ-9), and the Self-efficacy for Diabetes (SED). Symptom network analysis and network comparison test were used to construct and compare the depression-anxiety symptom network models of the female and male groups. Finally, we conducted flow diagrams to explore the symptoms directly or indirectly related to self-efficacy.

Results

The strongest edges in the depression-anxiety symptom networks are the edge between "GAD3" (Excessive worry) and "GAD4" (Trouble relaxing) and the edge between "PHQ1" (Anhedonia) and "PHQ4" (Energy) in the female and male groups, respectively. Most of the symptoms with the highest EI and bridge EI are related to worry and nervousness. Additionally, in the flow diagram of the female group, "PHQ6" (Guilt) has a high negative association with self-efficacy.

Conclusion

Females with diabetes are more vulnerable to depression and anxiety. Interventions targeting key symptoms in the network may be helpful in relieving the psychological problems among people with diabetes.

The relationship between patient empowerment and related constructs, affective symptoms and quality of life in patients with type 2 diabetes: a systematic review and meta-analysis

Introduction

The aim of this systematic review is to assess the relationship between patient empowerment and other empowerment-related constructs, and affective symptoms and quality of life in patients with type 2 diabetes.

Methods

A systematic review of the literature was conducted, according to the PRISMA guidelines. Studies addressing adult patients with type 2 diabetes and reporting the association between empowerment-related constructs and subjective measures of anxiety, depression and distress, as well as self-reported quality of life were included. The following electronic databases were consulted from inception to July 2022: Medline, Embase, PsycINFO, and Cochrane Library. The methodological quality of the included studies was analyzed using validated tools adapted to each study design. Meta-analyses of correlations were performed using an inverse variance restricted maximum likelihood random-effects.

Results

The initial search yielded 2463 references and seventy-one studies were finally included. We found a weak-to-moderate inverse association between patient empowerment-related constructs and both anxiety (r = -0.22) and depression (r = -0.29). Moreover, empowerment-related constructs were moderately negatively correlated with distress (r = -0.31) and moderately positively correlated with general quality of life (r = 0.32). Small associations between empowerment-related constructs and both mental (r = 0.23) and physical quality of life (r = 0.13) were also reported.

Discussion

This evidence is mostly from cross-sectional studies. High-quality prospective studies are needed not only to better understand the role of patient empowerment but to assess causal associations. The results of the study highlight the importance of patient empowerment and other empowerment-related constructs such as self-efficacy or perceived control in diabetes care. Thus, they should be considered in the design, development and implementation of effective interventions and policies aimed at improving psychosocial outcomes in patients with type 2 diabetes.

Vitality, mental health and role-physical mediate the influence of coping on depressive symptoms and self-efficacy in patients with non-alcoholic fatty liver disease: A cross-sectional study

OBJECTIVE

Our aim was to determine whether the association between active coping and depressive symptoms in patients with non-alcoholic fatty liver disease (NAFLD) was mediated by vitality, and whether diabetes and obesity could impact on this relationship. We also wanted to find out whether mental health and role-physical modulated the relationship between passive/avoidance coping and self-efficacy, and the role of liver fibrosis.

METHODS

Depressive symptoms (BDI-II), self-efficacy (GSE), coping (COPE-28) and quality of life (SF-12) were evaluated in 509 biopsy-proven NAFLD patients in this cross-sectional study. Mediation and moderated mediation models were conducted using the SPSS PROCESS v3.5 macro.

RESULTS

Vitality mediated the relationship between active coping and depressive symptoms (-2.254, CI = -2.792 to -1.765), with diabetes (-0.043, p = 0.017) and body mass index (BMI) (-0.005, p = 0.009) moderating the association. In addition, mental health (-6.435, CI = -8.399 to -4.542) and role-physical (-1.137, CI = -2.141 to -0.315) mediated the relationship between passive/avoidance coping and self-efficacy, with fibrosis stage (0.367, p < 0.001) moderating this association. Specifically, the presence of diabetes and significant fibrosis, and a higher BMI, were associated with greater negative impact on participant depressive symptoms or self-efficacy.

CONCLUSION

A maladaptive coping style was associated with poorer vitality, mental health and role-physical in NAFLD patients, which along with the presence of metabolic comorbidity (diabetes and obesity) and significant fibrosis predicted more depressive symptoms or poorer self-efficacy in these patients. These results suggested incorporating emotional and cognitive evaluation and treatment in patients with NAFLD.

The Association Between General Self-Efficacy and Depressive Symptoms in People with Type 2 Diabetes Mellitus: The Mediating Role of Coping Styles Preference

Background

Depressive symptoms are prevalent in persons with type 2 diabetes mellitus and related with poor disease outcomes. Both general self-efficacy and coping style are associated with depressive symptoms. A model about proactive coping indicates that coping style plays a mediation role between general self-efficacy and depressive symptoms. But, empirical evidence is missing about this potential mediation relationship which may be a barrier of taking precise strategies for relieving depressive symptoms.

Objective

This study aims to investigate the prevalence of elevated depressive symptoms in persons with type 2 diabetes mellitus and explore whether coping style preference mediates the association between general self-efficacy and depressive symptoms.

Methods

This was a secondary data analysis of a cross-sectional survey (June-July 2017) among 721 persons with type 2 diabetes mellitus (45.4% male and 54.6% female) aged from 22 to 96 years old. Data on general self-efficacy, coping style preference and depressive symptoms were collected using validated questionnaires in hospital setting. The mediation model was tested using the bootstrapping (K=5000) in the MPlus program version 7.4. The results were reported following the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

Results

The prevalence of elevated depressive symptoms was 58% (n = 418) among persons with type 2 diabetes mellitus at hospital setting. A higher level of general self-efficacy was related to less depressive symptoms via positive coping preference (p < 0.01).

Discussion

About two-thirds of persons with type 2 diabetes mellitus experienced elevated depressive symptoms during hospitalization. The intervention elements, including strengthening general self-efficacy and promoting positive coping, are promising to decrease their depressive symptoms.

Self-efficacy mediates the associations of diabetes distress and depressive symptoms with type 2 diabetes management and glycemic control

BACKGROUND

Adults with type 2 diabetes (T2D) often experience two common diabetes-related psychological distress: diabetes distress and depressive symptoms. Both are associated with adverse diabetes outcomes including poor self-management and glycemic control. However, diabetes distress and depressive symptoms differ in their associations with diabetes outcomes in T2D patients.

OBJECTIVE

This study proposes a hypothetical model to examine whether self-efficacy mediates the adverse effects of depressive symptoms and/or diabetes distress on self-care behaviors and glycemic control. Additionally, we examined the bi-directional relationships between diabetes distress and depressive symptoms to identify potential underlying mechanisms.

METHODS

This study conducted in 15 rural health clinics in Jiangsu province China. 900 adults with T2D participated in the prospective cohort study. The data Diabetes distress (the 17-item Diabetes Distress Scale, DDS17), depressive symptoms(the 10-item Center for Epidemiologic Studies Depression Scale, CESD-10), self-efficacy, self-care behaviors (diet and physical activity), metabolic variables (fasting plasma glucose, FPG) and demographic characteristics were assessed at baseline. Subsequent 12-month Hemoglobin A1C (HbA1c) were measured after baseline. Hierarchical multiple regression and bootstrap mediation analysis were used to test the effects and pathways among these associations.

RESULTS

Of 843 participants (93.67%) of total cohort with available subsequent 12-month HbA1c levels, mean age was 66.08 years and 66.55% were women, 25.15% of them had depressive symptoms (CES-D ≥ 10), 12.20% had moderate diabetes distress (mean DDS ≥2) and 4.98% had the both two psychological distress. Hierarchical multiple regression showed higher DDS score significantly predicted unhealthy diet(β = -1.10, P < 0.001) but not physical activities, while CESD score was negatively associated with physical activity (β = -0.06, P < 0.001) but not diet. No independent effects of the two psychological distress variables on subsequent 12-month HbA₁c were observed. Mediation analysis supported that elevated self-efficacy solely mediated the negative effect of both diabetes distress and depressive symptoms on diet (DDS score: β = -0.238, 95 BCE% CI [-0.350, -0.141]; CESD score: β = -0.010, 95 BCE% CI [-0.016, -0.005]), physical activities (DDS score: β = -0.446, 95 BCE% CI [-0.630, -0.283]; CESD score: β = -0.019, 95 BCE% CI [-0.030, -0.010]) and subsequent 12-month HbA1c (DDS score: β = 0.105, 95 BCE% CI [0.030,0.189]; CESD score: β = 0.004, 95 BCE% CI [0.001,0.009])_. Additionally, the interplay of diabetes distress and depressive symptoms exerts their effects on diabetes outcomes directly and indirectly via self-efficacy.

CONCLUSIONS

Self-efficacy may contribute to better diabetes outcomes and ameliorate negative effects of diabetes distress and depressive symptoms.

Mental health experiences with COVID-19 public health measures in an Alberta First Nations Community

BACKGROUND

First Nations (FN) people of Canada experience health, social, and systemic inequities due to colonization. Consequently, COVID-19 has placed further mental health stress on people related to personal finances, employment security and worry over infection, resulting in exacerbated effects of unresolved past medical and physical traumas. This study aims to understand the experiences related to mental health in an Alberta FN community during the early stages of the pandemic.

METHODS

In partnership with FN leadership, the study implemented an online cross-sectional survey. Adults from a large FN community in Alberta, Canada, were asked to complete a survey, including two mental health-related screening questionnaires: (1) Generalized Anxiety Disorder-2 item; and (2) Patient Health Questionnaire-2 item. In addition, respondents could provide responses to open-ended questions about their experiences.

RESULTS

Among 106 respondents, 95 (89.6%) finished the survey; 18% of adults screened positive for depressive symptoms (score of 3 or greater) and reported difficulty following public health advice for using hand sanitizer, maintaining social distancing, or self-isolating. 21% of adults screened positive for symptoms of anxiety (score of 3 or greater) and reported difficulty maintaining social distance, self-isolating, obtaining food and clothing, or meeting other basic living requirements.

CONCLUSIONS

FN communities may be disproportionately affected by COVID-19, and may experience exacerbated symptoms of anxiety, depression and overall poor mental health and well-being. Additional supports and services, including for mental health, should be considered for FN in the context of COVID-19 public health measures.

HIGHLIGHTS

The COVID-19 pandemic has brought upon increased stress and accompanying symptoms of anxiety and depression for a First Nations community in Alberta. Studies, such as this one, that characterize the influence of the COVID-19 pandemic on mental health among First Nations people, are urgently needed because of increasing demands on healthcare systems due to the pandemic and potential delays in the care of patients living with pre-existing mental health conditions. There is an opportunity to capitalize on First Nations people's experiences of post-traumatic growth proactively supporting/maintaining their well-being and possibly the development of community-based mental health interventions and supports.

Self-care and type 2 diabetes mellitus (T2DM): a literature review in sex-related differences

T2DM is a multifactorial disease, and it is considered a worldwide challenge for its increasing prevalence and its negative impact on patients' wellbeing. Even if it is known that self-care is a key factor in reaching optimal outcomes, and males and females implement different self-care behaviors, sex-related differences in self-care of patients with T2DM have been poorly investigated. Especially, an overall view of the available evidence has not yet been done. Accordingly, this review aims to summarize, critically review, and interpret the available evidence related to the sex-related differences in self-care behaviors of patients with T2DM. An extensive literature review was performed with a narrative synthesis following the PRISMA statement and flowchart through four databases: PubMed, CINAHL, Scopus, and Embase. From the 5776 identified records by the queries, only 29 articles were included, having a high-quality evaluation. Both females and males with T2DM must improve their self-care: more males reported performing better behaviors aimed at maintaining health and clinical stability (i.e., self-care maintenance) than females, but mainly in relation to physical activity. On the other hand, more females reported performing adequate behaviors aimed at monitoring their signs and symptoms (i.e., self-care monitoring) but with worse glycemic control and diabetic complications (i.e., self-care management). This review firstly provides an overall view of different self-care behaviors implemented by males and females with T2DM, showing that self-care management should be improved in both sexes. Health education must include the problems related to the diabetic pathology and the patient's own characteristics, such as sex.

The relationship between diabetes distress, medication taking, glycaemic control and self-management

Background Diabetes distress (DD) has broad-ranging effects on type 2 diabetes (T2DM) management and outcomes. DD research is scarce among ethnic minority groups, particularly Arabic-speaking immigrant communities. To improve outcomes for these vulnerable groups, healthcare providers, including pharmacists, need to understand modifiable predictors of DD. Aim To assess and compare DD and its association with medication-taking behaviours, glycaemic control, self-management, and psychosocial factors among first-generation Arabic-speaking immigrants and English-speaking patients of Anglo-Celtic background with diabetes, and determine DD predictors. Setting Various healthcare settings in Australia. Method A multicentre cross-sectional study was conducted. Adults with T2DM completed a survey comprised of validated tools. Glycated haemoglobin, blood pressure, and lipid profile were gathered from medical records. Multiple linear regression models were computed to assess the DD predictors. Main outcome measure Diabetes distress level. Results Data was analysed for 696 participants: 56.3% Arabic-speaking immigrants and 43.7% English-speaking patients. Compared with English-speaking patients, Arabic-speaking immigrants had higher DD, lower medication adherence, worse self-management and glycaemic control, and poorer health and clinical profile. The regression analysis demonstrated that higher DD in Arabic-speaking immigrants was associated with cost-related medication underuse and lower adherence to exercise, younger age, lower education level, unemployment, lower self-efficacy, and inadequate glycaemic control. Whereas among English-speaking patients, higher DD was associated with both cost- and non-cost-related underuse of medication and lower dietary adherence. Conclusion Results provided new insights to guide healthcare providers on reducing the apparent excess burden of DD among Arabic-speaking immigrants and potentially improve medication adherence, glycaemic control, and self-management.

Resilience as a Mediator of the Association Between Perceived Stigma and Quality of Life Among People With Inflammatory Bowel Disease

Background: Improving Quality of Life (QOL) is an essential objective in the management of inflammatory bowel disease. An accumulating body of research has been conducted to explore the association between perceived stigma and QOL among patients with chronic illness. Still, underlying mechanisms behind this pathway have not been thoroughly examined. Objective: To investigate (a) the effect of perceived stigma on QOL among patients with inflammatory bowel disease; and (b) the mediating role of resilience in the association between perceived stigma and QOL. Methods: This cross-sectional study included a convenient sample of patients diagnosed with inflammatory bowel disease from four tertiary hospitals in Jiangsu Province, China. Patients completed the Perceived Stigma Scale in Inflammatory Bowel Disease (PSS-IBD), the Resilience Scale for Patients with Inflammatory Bowel Disease (RS-IBD), and the Inflammatory Bowel Disease Questionnaire (IBDQ). A bootstrapping analysis was implemented using the SPSS macro PROCESS. Results: A total of 311 patients with Cohn's disease and ulcerative colitis participated in this study, and 57.6% were men. The mean disease duration was 3.51 ± 1.04 years. Approximately 40% of the sample exceeded the criterion score for moderate stigma. Patients who perceived moderate or severe stigma reported lower QOL compared with those with mild stigma. After controlling for sociodemographic and clinical variables, we observed that perceived stigma was negatively associated with resilience. Moreover, resilience was found to mediate the relationship between perceived stigma and all aspects of QOL. Conclusions: These findings suggested that QOL of patients with inflammatory bowel disease was associated with perceived stigma and resilience and identified the mediating effects of resilience in the relationship between perceived stigma and QOL. Furthermore, this suggests that integrating intervention techniques to target resilience into the QOL improvement program of individuals with perceived stigma is possible.

Type D Personality Is Associated with Glycemic Control and Socio-Psychological Factors on Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Study

Purpose

Type D personality (TDP) has been recognized as a risk factor for many diseases. The aims of our study were to estimate the prevalence of TDP and glycemic control on the patients with type 2 diabetes mellitus (T2DM) and to assess their relationship between TDP and socio-psychological factors, such as perceived stress, self-efficacy, self-care behaviors, and psychological distress.

Patients and Methods

A total of 198 T2DM patients (male 62.6%, mean age 51.2±11.0, mean HbA1c 7.3±1.8%) were recruited consecutively from the Department of Endocrinology of a regional hospital in Taipei, Taiwan, from December 2017 to April 2018. They completed questionnaires that contain questions about sociodemographic characteristics, TDP, illness-related stress, self-efficacy, execution of diabetes management and emotional distress. Their medical records were reviewed for biomedical data.

Results

Of the 198 patients, 82 (41.4%) had TDP. Controlling for sociodemographic factors, patients with TDP were reported significantly poorer on glycemic control than those without TDP (mean HbA1c (%) 7.6±1.9 vs 7.1±1.8, P<0.05). Compared to those without TDP, the results showed significantly higher levels of perceived stress (P<0.001) and psychological distress (anxiety and depression) (P<0.001), as well as significantly lower levels of self-efficacy (P<0.001) and self-care behaviors (P<0.001) on patients with TDP. TDP was positively correlated with perceived stress and psychological distress and negatively correlated with self-efficacy and self-care behaviors scores.

Discussion

This study provides the evidence linking TDP with poor glycemic control, low levels of self-efficacy and self-care behaviors, as well as high levels of perceived stress and psychological distress, which highlights the screening of TDP and the tailored needs for the care among T2DM patients with TDP.

Individual differences in impulsivity and need for cognition as potential risk or resilience factors of diabetes self-management and glycemic control

Objective

Impulsivity is marked by insufficient reflection and forethought, whereas Need for Cognition (NFC) also referred to as cognitive motivation or intellectual engagement is marked by elaborated thinking. The aim of this study was to investigate the potential role of these personality traits as resilience or risk factors, respectively, in diabetes self-management and glycaemic control. Further, it was examined whether diabetes-specific self-efficacy could serve as a mediator of these relationships.

Design/Measures

Data of 77 participants with type 2 diabetes was ascertained, using self-report instruments for NFC, impulsivity, diabetes-specific self-efficacy, and diabetes self-management. Glycemic control was assessed by the biomarker HbA_1c.

Results

While NFC was strongly positively associated with diabetes self-management and glycemic control, impulsivity showed a reverse pattern. Results of simple and serial mediation models showed that the effects on diabetes self-management and HbA1c of both, impulsivity and NFC, were mediated by self-efficacy.

Conclusion

The moderate to high standardized coefficients suggests that NFC might be an important protective factor and impulsivity a possible risk factor for effective diabetes self-management and glycemic control. These traits could be applied for an easy-to-use questionnaire-based patient screening, enabling trait-tailored treatments and programs which in turn may lower economic and health costs associated with poor diabetes-care.

The prevalence of comorbid depression in patients with type 2 diabetes: an updated systematic review and meta-analysis on huge number of observational studies

AIMS

Depression is a common co-morbidity in patients with type 2 diabetes mellitus (T2DM). Untreated depression in these patients adversely affects self-care activities and other diabetes complications. The aim of this study is to estimate the prevalence of depression among patients with T2DM by conducting a meta-analysis of observational studies.

METHODS

MEDLINE, Web of Science, Science Direct, and Google Scholar databases were searched for all observational studies that assessed depression in T2DM. Relevant articles were searched using the combination of Medical Subject Heading (MeSH) terms of "depression", "depressive disorder", and "diabetes mellitus" published between January 2007 and July 2018. Random effects model was used to estimate the weighted prevalence rates and 95% CI using "metaprop program in STATA 11".

RESULTS

In total, the 248 included studies (with 273 reported prevalence) identified 83,020,812 participants; of them, 23,245,827 (28%; 95% CI 27, 29) suffered from different severity levels of depressive disorders. The prevalence of depression was separately reported in 137,372 males and 134,332 females. Of them, 31,396 males (23%, 95% CI: 20, 26) and 45,673 females (34%, 95% CI: 31, 38) were depressed. Compared with global estimate, depression prevalence was lower in Europe (24%) and Africa (27%), but higher in Australia (29%) and Asia (32%). The prevalence in America was equal to the estimated prevalence in the world (28%). Depression was more common in subjects younger than 65 compared with elderlies (31% vs. 21%).

CONCLUSION

Our findings demonstrated that almost one in four adults with T2DM experienced depression. Given the high prevalence of depressive disorders in diabetic patients, screening these patients for co-morbid depression and its relevant risk factors is highly recommended.

Sex, race, and the role of relationships in diabetes health: intersectionality matters

Previous research has seldom used an intersectionality framework to consider how sex and race affect diabetes health, nor has it examined the role of sex and race in the well-established link between romantic relationship quality and health. This study targeted 200 adults with type 2 diabetes (46% Black; 45% female) and examined whether sex, race, and the interaction between sex and race predicted behavioral and psychological health, or moderated the link between relationship quality and health outcomes. Black women reported poorer diabetes self-care and lower self-efficacy compared to other groups. Relationship quality was associated with better self-care, increased self-efficacy, and lower depressive symptoms. The association between relationship quality and medication adherence was stronger for Black women, and the association between relationship quality and self-efficacy was stronger for both Black women and White men. Results suggest that Black women with diabetes experience more health disadvantages than other groups, but some of these disadvantages might be attenuated by supportive romantic relationships.

Anxiolytic-Like and Antidepressant-Like Effects of Resveratrol in Streptozotocin-Induced Diabetic Rats

Introduction

Diabetes is associated with anxiety and depression. Resveratrol, one of the most potent natural polyphenols with antioxidant properties, has been demonstrated to have benefits against diabetes. In the current study, we investigated the effects of resveratrol on depression and anxiety-like behaviors in diabetic rats.

Methods

Adult male Wistar albino rats were assigned for control and diabetic groups, and these groups were divided into four subgroups as follows: Saline-treated, DMSO-treated, resveratrol-treated and imipramine-treated animals (n=10). Diabetes was induced by a single intraperitoneal injection of streptozotocin (STZ) (50 mg/kg), and 2 days after the STZ injection the rats having hyperglycemia (>300 mg/dl) were assigned to be diabetic. Rats in treatment groups were injected intraperitoneally with resveratrol (20 mg/kg) and imipramine (10 mg/kg) for 4 weeks. After 4-week-treatment period, tail suspension test (TST), forced swimming test (FST), elevated plus maze test (EPM) and locomotor activity test were performed. Blood samples were collected to estimate serum superoxide dismutase (SOD) and NADPH oxidase (Nox) levels.

Results

Diabetic rats displayed depressive-like behaviors in the FST and TST, and anxiety-like behaviors in the EPM. Resveratrol and imipramine decreased anxiety-like and depressive-like behaviors without affecting locomotor activity in diabetic rats. A significant reduction in SOD levels and a marked increase in Nox levels were observed in diabetic rats. Resveratrol treatment normalized these levels, while imipramine did not affect neither SOD nor Nox levels.

Conclusion

This study indicates that chronic resveratrol treatment may able to treat comorbid anxiety-and depressive-like behaviors in diabetes through inhibition of oxidative stress.

The Effect of Depression on Poor Glycemic Control in Adults with Type 2 Diabetes: The Mediating Roles of Self-Efficacy and Self-Management Behaviors

<b><i>Background:</i></b> High levels of depression and poor self-efficacy and self-management are associated with worse glycemic control, but the linkage and pathway between these variables are poorly understood. We conducted this study to investigate the hypothesis that self-efficacy and self-management mediate the influence of depression on poor glycemic control. <b><i>Methods:</i></b> We studied a purposive sample of 142 adults with type 2 diabetes attending a public clinic in Ilam, Iran. Hierarchical linear regression analysis and structural equation modeling were used to explore the relationships among the variables of interest. <b><i>Result:</i></b> Depression directly and negatively affects self-efficacy and indirectly affects self-management behaviors, which in turn have direct effects on hemoglobin A1c (HbA1c). Self-efficacy mediates the relationship between depression and self-management behaviors. Self-efficacy and self-management behaviors partially mediate the effect of depression on HbA1c. These results confirmed that the data fit the hypothesized model very well. <b><i>Conclusion:</i></b> Careful monitoring of glycemic control might be important in those individuals who exhibit clinical signs of depression. Effective treatment programs should probably pay close attention to not only screening and treatment of depression but also skills training to enhance patient self-efficacy and self-management of diabetes to improve HbA1c.

Validation of the shortened Perceived Medical Condition Self-Management Scale in patients with chronic disease

Self-efficacy, or perceived competence, has been identified as an important factor in self-management behaviors and health outcomes in patients with chronic disease. Measures of self-management self-efficacy are currently available for multiple forms of chronic disease. One established measure is the 8-item Perceived Medical Condition Self-Management Scale (PMCSMS). This study investigated the use of the PMCSMS in samples of patients with a chronic disease to develop an abbreviated version of the scale that could be more readily used in clinical contexts or in large population health cohort studies. The PMCSMS was administered as either a generic scale or as a disease-specific scale. The results of analyses using item response theory and classical test theory methods indicated that using 4 items of the scale resulted in similar internal consistency (α = .70-0.90) and temporal stability (test-retest r = .75 after 2 to 4 weeks) to the 8-item PMCSMS (r = .81 after 2 to 4 weeks). The 4 items selected had the greatest discriminability among participants (α parameters = 2.49-3.47). Scores from both versions also demonstrated similar correlations with related constructs such as health literacy (r = .13-0.29 vs. 0.14-0.27), self-rated health (r = .17-0.48 vs. 0.26-0.50), social support (r = .21-0.32 vs. 0.25-0.34), and medication adherence (r = .20-0.24 vs. 0.20-0.25). The results of this study indicate that 4-item PMCSMS scores are equally valid but more efficient, and have the potential to be beneficial for both research and clinical applications.

Subthreshold depression among diabetes patients in Beijing: Cross-sectional associations among sociodemographic, clinical, and behavior factors

BACKGROUND

This study explores the prevalence of subthreshold depression (SubD) and its association with factors in type 2 diabetes mellitus (T2DM) patients.

METHODS

This cross-sectional study involved 808 outpatients with T2DM from ten hospitals in Beijing between September 2015 and January 2016. All participants completed the Patient Health Questionnaire 9-item (PHQ-9) to evaluate depressive status, with scores between 5 and 14 considered SubD. Conditional logistic regression was conducted to investigate the variables associated with SubD in T2DM patients.

RESULTS

T2DM patients with SubD comprised 11.6% (n = 94) of the sample. The odd ratios for the variables having significant positive associations with SubD were: being a women (OR = 1.90; 95%CI: 1.09-3.32), divorced/widowed (OR = 3.27; 95%CI: 1.46-7.30), comorbidity of cerebrovascular disease (OR = 2.00; 95%CI: 1.06-3.76), more diabetic complications (OR = 8.04; 95%CI: 2.77-23.31), and higher HbA1c in men (OR = 2.41; 95%CI: 1.25-4.64). Being older (OR = 0.78; 95%CI: 0.62-0.98), exercising more (OR = 0.44; 95%CI: 0.22-0.91) and poverty (OR = 0.36; 95%CI: 0.19-0.69) were negatively related to SubD.

LIMITATIONS

The sample was mainly recruited from hospital settings, which limits generalization. The study's cross-sectional design precludes making causal inferences.

CONCLUSIONS

The proportion of SubD was estimated to be 11.6% among T2DM patients in Beijing. Having more diabetic complications and being divorced/widowed made the odds of having SubD 8-fold and 3-fold higher than not having it, respectively. The relationship between SubD and diabetes necessitates early screening for milder forms of depression, which can alleviate the social burden and individual impairment from major depression or other chronic diseases.

Sex differences in the association of psychological status with measures of physical activity and sedentary behaviour in adults with type 2 diabetes

AIM

To assess the association of psychological variables on leisure-time physical activity and sedentary time in men and women with type 2 diabetes mellitus (T2D).

METHODS

In this cross-sectional study, we evaluated 163 patients with T2D, consecutively recruited at the Diabetes Centre of the Verona General Hospital. Scores on depression and anxiety symptoms, psychosocial factors (including self-efficacy, perceived interference, perceived severity, social support, misguided support behaviour, spouse's positive behaviour), physical activity and time spent sitting were ascertained using questionnaires responses to the Beck Depression Inventory-II, Beck Anxiety Inventory, Multidimensional Diabetes Questionnaire, International Physical Activity Questionnaire.

RESULTS

Physical activity was significantly associated with higher social support in women and with increased self-efficacy in men. Sedentary time was significantly associated with higher perceived interference, anxiety and depressive symptoms, and with reduced diabetes self-efficacy in women, while it was associated solely with anxiety in men. Depressive symptoms and self-efficacy in women and anxiety symptoms in men were independent predictors of sedentary time when entered in a multivariable regression model also including age, BMI, haemoglobin A1c, diabetes duration, perceived interference and self-efficacy as covariates.

CONCLUSIONS

Lower self-efficacy and higher symptoms of depression were closely associated with increased sedentary time in women, but not in men, with T2D. It is possible that individualized behavioural interventions designed to reduce depressive symptoms and to improve diabetes self-efficacy would ultimately reduce sedentary behaviours, particularly in women with T2D.

When knowing is not enough: Emotional distress and depression reduce the positive effects of health literacy on diabetes self-management

OBJECTIVES

Adequate self-management activities are important predictors of diabetes outcomes. As diabetes literacy and self-efficacy are strong predictors of diabetes self-care, self-management education programs focus essentially on these factors. This study investigated whether emotional distress or depression moderates the relation between health literacy, self-efficacy and diabetes self-care behaviors.

METHODS

128 people with type 2 diabetes were recruited in hospitals, through general practitioners and via a diabetes website, and completed a questionnaire assessing health literacy, self-efficacy, diabetes-related distress, depression and self-care behaviors.

RESULTS

Multiple regression analysis confirms that health literacy and self-efficacy significantly predict reported self-care behaviors. Additional regression analyses reveal that distress or depression do not predict self-care behaviors directly, but moderate the effect of health literacy, which has a weaker impact in patients experiencing distress or depression. In contrast, distress and depression do not moderate the effect of self-efficacy on diabetes self-care behaviors.

CONCLUSION

Emotional distress, whether related to diabetes or not, prevents patients from acting on their competence to perform adequate self-management behaviors.

PRACTICE IMPLICATIONS

Diabetes Professionals should pay more attention to the patients' affective state and its influence on self-care. Psychological support should be integrated in the care for people suffering from type 2 diabetes.

Depressive symptoms are associated with poor glycemic control among women with type 2 diabetes mellitus

Objective

In patients with type 2 diabetes mellitus, depressive symptoms may be associated with metabolic deterioration. The impact of sex on this association is unclear. The aim of this study is to analyze the relationship between depression and metabolic control by sex. The data presented is the side product of the clinical investigation by Rui Duarte, MD, Treatment Response in Type 2 Diabetes Patients with Major Depression from 2007.

Results

A sample of 628 outpatients with type 2 diabetes mellitus was taken from a specialized diabetes outpatient clinic. In a univariate analysis: women’s glycohemoglobin mean levels were 8.99% whereas men’s were 8.41% and the difference was statistically significant. The proportion of women (34.3%) with pathological levels of depression (Hospital Anxiety Depression Scale score ≥ 8) was significantly higher than men’s (15.2%). A linear regression analysis performed by sex and controlling for demographic, clinical and psychological variables, showed poorer metabolic control in women with depressive symptoms. No association was observed in men. These results support depression as a predictor for poor metabolic control in women and the need for detecting depressive symptoms when glycemic levels deteriorate.

Population attributable fractions for Type 2 diabetes: an examination of multiple risk factors including symptoms of depression and anxiety

BACKGROUND

Population attributable fractions (PAFs) are frequently used to quantify the proportion of Type 2 diabetes cases due to single risk factors, an approach which may result in an overestimation of their individual contributions. This study aimed to examine Type 2 diabetes incidence associated with multiple risk factor combinations, including the metabolic syndrome, behavioural factors, and specifically, depression and anxiety.

METHODS

Using data from the population-based HUNT cohort, we examined incident diabetes in 36,161 Norwegian adults from 1995 to 2008. PAFs were calculated using Miettinen's case-based formula, using relative risks estimated from multivariate regression models.

RESULTS

Overall, the studied risk factors accounted for 50.5% of new diabetes cases (78.2% in men and 47.0% in women). Individuals exposed to both behavioural and metabolic factors were at highest risk of diabetes onset (PAF = 22.9%). Baseline anxiety and depression contributed a further 13.6% of new cases to this combination. Men appeared to be particularly vulnerable to the interaction between metabolic, behavioural and psychological risk factors.

CONCLUSION

This study highlights the importance of risk factor clustering in diabetes onset, and is the first that we know of to quantify the excess fraction of incident diabetes associated with psychological risk factor interactions.

Symptoms of anxiety and depression in type 2 diabetes: Associations with clinical diabetes measures and self-management outcomes in the Norwegian HUNT study

OBJECTIVE

To determine if symptoms of depression and anxiety are differentially associated with clinical diabetes measures and self-management behaviours in individuals with Type 2 diabetes, and whether these associations vary by patient sex.

RESEARCH DESIGN AND METHODS

A cross-sectional analysis using data from 2035 adults with Type 2 diabetes in the Nord-Trøndelag Health Study. Multivariate logistic regression was used to explore associations between symptoms of depression and anxiety and waist girth, HDL cholesterol, systolic blood pressure, triglycerides, c-reactive protein, glycemic control, diet adherence, exercise, glucose monitoring, foot checks for ulcers, and the subjective patient experience. Analyses were stratified by sex.

RESULTS

Depression was associated with a lower likelihood of avoiding saturated fats (OR=0.20 [95% CI: 0.06, 0.68]) and increased odds of physical inactivity (OR=1.69 [95% CI: 1.37, 2.72]). Anxiety was associated with increased odds of eating vegetables (OR=1.66 [95% CI: 1.02, 2.73]), and an over two-fold increase of feeling that having diabetes is difficult. In women, anxiety was associated with elevated c-reactive protein levels (OR=1.57 [95% CI: 1.05, 2.34]). In men, depressive symptoms were associated with elevated HbA1c (OR=5.00 [95% CI: 1.15, 8.23).

CONCLUSIONS

Symptoms of depression and anxiety were differentially associated with some key diabetes-related measures. Our results suggest sex-specific differences with respect to two important clinical outcomes (i.e., anxiety and CRP in women and depression and glycemic control in men). These findings should alert practitioners to the importance of detection and management of psychological symptoms in individuals with Type 2 diabetes.

Psychological interventions for diabetes-related distress in adults with type 2 diabetes mellitus

BACKGROUND

Many adults with type 2 diabetes mellitus (T2DM) experience a psychosocial burden and mental health problems associated with the disease. Diabetes-related distress (DRD) has distinct effects on self-care behaviours and disease control. Improving DRD in adults with T2DM could enhance psychological well-being, health-related quality of life, self-care abilities and disease control, also reducing depressive symptoms.

OBJECTIVES

To assess the effects of psychological interventions for diabetes-related distress in adults with T2DM.

SEARCH METHODS

We searched the Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, BASE, WHO ICTRP Search Portal and ClinicalTrials.gov. The date of the last search was December 2014 for BASE and 21 September 2016 for all other databases.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) on the effects of psychological interventions for DRD in adults (18 years and older) with T2DM. We included trials if they compared different psychological interventions or compared a psychological intervention with usual care. Primary outcomes were DRD, health-related quality of life (HRQoL) and adverse events. Secondary outcomes were self-efficacy, glycosylated haemoglobin A1c (HbA1c), blood pressure, diabetes-related complications, all-cause mortality and socioeconomic effects.

DATA COLLECTION AND ANALYSIS

Two review authors independently identified publications for inclusion and extracted data. We classified interventions according to their focus on emotion, cognition or emotion-cognition. We performed random-effects meta-analyses to compute overall estimates.

MAIN RESULTS

We identified 30 RCTs with 9177 participants. Sixteen trials were parallel two-arm RCTs, and seven were three-arm parallel trials. There were also seven cluster-randomised trials: two had four arms, and the remaining five had two arms. The median duration of the intervention was six months (range 1 week to 24 months), and the median follow-up period was 12 months (range 0 to 12 months). The trials included a wide spectrum of interventions and were both individual- and group-based.A meta-analysis of all psychological interventions combined versus usual care showed no firm effect on DRD (standardised mean difference (SMD) -0.07; 95% CI -0.16 to 0.03; P = 0.17; 3315 participants; 12 trials; low-quality evidence), HRQoL (SMD 0.01; 95% CI -0.09 to 0.11; P = 0.87; 1932 participants; 5 trials; low-quality evidence), all-cause mortality (11 per 1000 versus 11 per 1000; risk ratio (RR) 1.01; 95% CI 0.17 to 6.03; P = 0.99; 1376 participants; 3 trials; low-quality evidence) or adverse events (17 per 1000 versus 41 per 1000; RR 2.40; 95% CI 0.78 to 7.39; P = 0.13; 438 participants; 3 trials; low-quality evidence). We saw small beneficial effects on self-efficacy and HbA1c at medium-term follow-up (6 to 12 months): on self-efficacy the SMD was 0.15 (95% CI 0.00 to 0.30; P = 0.05; 2675 participants; 6 trials; low-quality evidence) in favour of psychological interventions; on HbA1c there was a mean difference (MD) of -0.14% (95% CI -0.27 to 0.00; P = 0.05; 3165 participants; 11 trials; low-quality evidence) in favour of psychological interventions. Our included trials did not report diabetes-related complications or socioeconomic effects.Many trials were small and were at high risk of bias for incomplete outcome data as well as possible performance and detection biases in the subjective questionnaire-based outcomes assessment, and some appeared to be at risk of selective reporting. There are four trials awaiting further classification. These are parallel RCTs with cognition-focused and emotion-cognition focused interventions. There are another 18 ongoing trials, likely focusing on emotion-cognition or cognition, assessing interventions such as diabetes self-management support, telephone-based cognitive behavioural therapy, stress management and a web application for problem solving in diabetes management. Most of these trials have a community setting and are based in the USA.

AUTHORS' CONCLUSIONS

Low-quality evidence showed that none of the psychological interventions would improve DRD more than usual care. Low-quality evidence is available for improved self-efficacy and HbA1c after psychological interventions. This means that we are uncertain about the effects of psychological interventions on these outcomes. However, psychological interventions probably have no substantial adverse events compared to usual care. More high-quality research with emotion-focused programmes, in non-US and non-European settings and in low- and middle-income countries, is needed.

The association between cognitive decline and incident depressive symptoms in a sample of older Puerto Rican adults with diabetes

BACKGROUND

Older Puerto Rican adults have particularly high risk of diabetes compared to the general US population. Diabetes is associated with both higher depressive symptoms and cognitive decline, but less is known about the longitudinal relationship between cognitive decline and incident depressive symptoms in those with diabetes. This study investigated the association between cognitive decline and incident depressive symptoms in older Puerto Rican adults with diabetes over a four-year period.

METHODS

Households across Puerto Rico were visited to identify a population-based sample of adults aged 60 years and over for the Puerto Rican Elderly: Health Conditions study (PREHCO); 680 participants with diabetes at baseline and no baseline cognitive impairment were included in analyses. Cognitive decline and depressive symptoms were measured using the Mini-Mental Cabán (MMC) and Geriatric Depression Scale (GDS), respectively. We examined predictors of incident depressive symptoms (GDS ≥ 5 at follow-up but not baseline) and cognitive decline using regression modeling.

RESULTS

In a covariate-adjusted logistic regression model, cognitive decline, female gender, and greater diabetes-related complications were each significantly associated with increased odds of incident depressive symptoms (p < 0.05). In a multiple regression model adjusted for covariates, incident depressive symptoms and older age were associated with greater cognitive decline, and higher education was related to less cognitive decline (p < 0.05).

CONCLUSIONS

Incident depressive symptoms were more common for older Puerto Ricans with diabetes who also experienced cognitive decline. Efforts are needed to optimize diabetes management and monitor for depression and cognitive decline in this population.

Psychological distress, self-efficacy and glycemic control in type 2 diabetes

AIM

To investigate the association of glycemic control with depression, anxiety, self-efficacy and other diabetes-specific psychological measures in a cohort of adult patients with type 2 diabetes (T2D) free of severe chronic diabetes-related complications.

METHODS AND RESULTS

In 172 T2D outpatients consecutively recruited at the Diabetes Center of Verona City Hospital, we performed a standard medical assessment and completed the Beck Depression Inventory-II (BDI-II), the Beck Anxiety Inventory (BAI) and the Multidimensional Diabetes Questionnaire (MDQ) Age, body mass index (BMI) and glycosylated hemoglobin (HbA1c) were (median [IQR]): 64.0 [58.0-69.0] years, 31.0 [28.0-34.4] kg/m², and 7.3 [6.7-8.0] %, respectively. The overall prevalence of anxiety and depression was 14.5% and 18.6%, respectively. Higher levels of HbA1c were significantly (p < 0.001) associated with a number of MDQ dimensions, such as higher perceived interference with daily activities (Spearman's rho coefficient = 0.33), higher perceived diabetes severity (rho = 0.28) and lower self-efficacy (rho = -0.27), but not with depression or anxiety. These three variables were also independent predictors of higher HbA1c levels, when entered in a multivariable stepwise-forward regression model that also included age, BMI, diabetes duration and diabetes-specific social support as covariates.

CONCLUSION

Lower self-efficacy and higher diabetes distress were closely associated with poorer glycemic control. No direct association between HbA1c and clinical psychological symptoms was detected. These results highlight that a number of diabetes-specific psychological variables may play a role amidst psychological distress and glycemic control. Further studies are needed to elucidate the relevance of diabetes distress and self-efficacy to the achievement of individual glycemic targets.

Type 2 Diabetes and Comorbid Symptoms of Depression and Anxiety: Longitudinal Associations With Mortality Risk

OBJECTIVE

Depression is strongly linked to increased mortality in individuals with type 2 diabetes. Despite high rates of co-occurring anxiety and depression, the risk of death associated with comorbid anxiety in individuals with type 2 diabetes is poorly understood. This study documented the excess mortality risk associated with symptoms of depression and/or anxiety comorbid with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Using data for 64,177 Norwegian adults from the second wave of the Nord-Trøndelag Health Study (HUNT2), with linkage to the Norwegian Causes of Death Registry, we assessed all-cause mortality from survey participation in 1995 through to 2013. We used Cox proportional hazards models to examine mortality risk over 18 years associated with type 2 diabetes status and the presence of comorbid affective symptoms at baseline.

RESULTS

Three clear patterns emerged from our findings. First, mortality risk in individuals with diabetes increased in the presence of depression or anxiety, or both. Second, mortality risk was lowest for symptoms of anxiety, higher for comorbid depression-anxiety, and highest for depression. Lastly, excess mortality risk associated with depression and anxiety was observed in men with diabetes but not in women. The highest risk of death was observed in men with diabetes and symptoms of depression only (hazard ratio 3.47, 95% CI 1.96, 6.14).

CONCLUSIONS

This study provides evidence that symptoms of anxiety affect mortality risk in individuals with type 2 diabetes independently of symptoms of depression, in addition to attenuating the relationship between depressive symptoms and mortality in these individuals.

Type D personality as a predictor of self-efficacy and social support in patients with type 2 diabetes mellitus

OBJECTIVE

The aim of this study was to estimate the prevalence of Type D personality and assess the relationship between this personality type and self-efficacy/social support in Chinese patients with type 2 diabetes mellitus (T2DM).

PATIENTS AND METHODS

From January 1, 2014, to July 31, 2014, 532 consecutive patients with T2DM were recruited from two hospitals in Guangzhou, China. The participants completed questionnaires containing questions about sociodemographic characteristics, Type D personality, self-efficacy, and social support scales, and their medical records were reviewed for additional data.

RESULTS

Of the 532 patients, 18.2% had Type D personality. Patients with this personality type reported significantly lower levels of self-efficacy (P<0.001), total social support (P<0.001), subjective support (P<0.001), and support utilization (P=0.003), but similar level of objective support (P=0.314), compared to those of patients without Type D personality. Negative affectivity and social inhibition, two intrinsic traits of Type D personality, negatively correlated with self-efficacy and social support scores. Type D personality was significantly associated with less self-efficacy and social support (P<0.001), controlling for other sociodemographic factors. Glycosylated hemoglobin (HbA1c) levels were significantly higher in T2DM patients with Type D personality than in patients with non-Type D personality.

CONCLUSION

This study provides new evidence linking Type D personality with self-efficacy, social support, and poor glycemic control, highlighting the special need for care among T2DM patients with Type D personality.

Self-Care Adherence and Psychological Functioning of Older Patients with Type 2 Diabetes: Effects of Persuasion, Social Pressure, and Self-Efficacy

This cross-sectional study examined the role of family members' use of persuasion versus pressure as distinct forms of social control by which family members attempt to encourage better diabetes management among older adults with type 2 diabetes mellitus (T2DM). The study also examined how self-efficacy might moderate the relationship between persuasion/pressure, psychological functioning, and self-care adherence. Participants were 96 men and 103 women with T2DM, with a mean age of 63.3 years. Regression results show that neither persuasion nor pressure was significantly related to self-care adherence, but persuasion and pressure were associated in complex ways with diabetes-related emotional distress and depressive symptoms for which significant interaction effects were found. Patients with lower self-efficacy benefited from persuasion, but were adversely affected by pressure. In contrast, patients with higher self-efficacy were adversely affected by persuasion, but were less negatively affected by pressure. Findings highlight the importance of reducing pressure-based social control, considering patients' self-efficacy when family members seek to influence patients' self-care behaviors, and targeting patient-family interactions in future interventions.

Exercise barriers and the relationship to self-efficacy for exercise over 12 months of a lifestyle-change program for people with heart disease and/or diabetes

BACKGROUND

Barriers to exercise are common in people with coronary heart disease (CHD) and/or diabetes mellitus (DM), and may influence self-efficacy for exercise.

PURPOSE

The purpose of this study was to describe the exercise barriers experienced by people who have CHD and/or DM participating in the Healthy Eating and Exercise Lifestyle Program and to determine whether these barriers influence self-efficacy.

METHODS

Participants ( n = 134) identified their barriers to exercise and completed the self-efficacy for exercise survey at baseline, at 4 months (following structured and supervised exercise) and at 12 months (following home-based exercise with three follow-up calls).

RESULTS

The sample mean age was 63.6 years (SD 8.5) and 58% were male. Barriers to exercise were reported by 88% at baseline, 76% at 4 months, and 47% at 12 months. The most common barriers were lack of motivation (40.3%), lack of time overall (30.6%), and lack of time due to family commitments (17.2%). Only motivation changed significantly over time from baseline (40%) to 4 months (23%, p = 0.040). Lower self-efficacy for exercise was associated with lack of motivation at 12 months only, more depressive symptoms at baseline and 4 months, and a CHD diagnosis and higher body mass index at 12 months. In contrast, male gender and having higher self-efficacy at baseline were associated with higher self-efficacy for exercise at 4 and 12 months.

CONCLUSION

Patients identified many exercise barriers despite participating in a lifestyle-change program. Lack of motivation negatively influenced self-efficacy for exercise at 12 months. Other factors needing attention include baseline self-efficacy, depressive symptoms, being female, being more overweight, and having CHD.

Mobile Phone and Web-based Cognitive Behavior Therapy for Depressive Symptoms and Mental Health Comorbidities in People Living With Diabetes: Results of a Feasibility Study

BACKGROUND

Depression is often comorbid with diabetes; however, undertreatment of depressive symptoms in people affected is common.

OBJECTIVE

We studied preliminary acceptability and effectiveness of a fully automated, mobile phone, and web-based public health intervention, myCompass, for reducing depressive symptoms and improving mental health comorbidities in people with diabetes.

METHODS

In this single-group feasibility study, 89 volunteers with type 1 (n=34) or type 2 (n=55) diabetes and at least mild depressive symptoms used myCompass for 7 weeks. Web-based measures of depressive and anxious symptoms, functional impairment, diabetes-specific variables, and user satisfaction were completed at baseline, postintervention, and 3-month follow-up.

RESULTS

Retention rates were 54% (n=48) at postintervention and 36% (n=32) at follow-up. Depressive symptoms were significantly improved at postintervention (P<.001; within-group effect size d=1.05), with gains persisting at follow-up. Mental health comorbidities, including anxiety (P<.001), functioning (P<.001), and diabetes-specific distress (P<.001), also showed significant and sustained improvement. Satisfaction with myCompass was high, with convenience and ease of program use, and relevance of program content rated positively by participants.

CONCLUSIONS

The myCompass program shows promise as an acceptable and effective treatment for depression and comorbid mental health problems in people with diabetes. The program is broadly available, free to use, and may benefit patients with diabetes who do not access services and/or wish to manage their mental health themselves. Replication of these findings in a controlled study is warranted.

The relationships among depression, self-care agency, self-efficacy and diabetes self-care management

At the time the study was conducted, Besher Gharaibeh, Byron Gajewski, and Diane Boyle were affiliated with School of Nursing University of Kansas, 3901 Rainbow Boulevard, Kansas City, KS 66160, USA; Ahmed Al-smadi was affiliated with University of Ulster, Belfast, Newtownabbey Co. Antrim BT37 0QB, Jordandtown road, UK. The coexistence of diabetes and depression is associated with negative outcomes such as poor diabetes self-care management (DSCM). Complex relationships exist among diabetes knowledge, self-efficacy, self-care agency, depression and DSCM. No study has examined the relationships among all these factors at the same time. We aimed to examine relationships among depression, diabetes knowledge, self-care agency, self-efficacy and DSCM in insulin- treated people based on a modification of the DSCM model. A cross-sectional, correlational model testing design was used. Participants with type 1 ( n = 35) and type 2 ( n = 43) diabetes were recruited from both outpatient and community sites. Participants mean age was 46.6 years (standard deviation 13.7) and the majority were men (56.4%). Multiple regression analyses tested the hypothesised relationships. Depression was found to have a direct negative relationship with self-care agency and self-efficacy. The relationship between depression and DSCM was not direct. Self-care agency and self-efficacy completely mediated the effect of depression on DSCM. Self-efficacy completely mediated the effect of self-care agency on DSCM. We conclude that effective treatment programmes for persons managed with insulin should probably include not only screening and treatment of depression, but also skills training to enhance patient self-care agency and self-efficacy alongside DSCM.

Depression and Diabetes in a Primarily African American Female Population

Depression is one of the most serious mental health comorbidities associated with diabetes. In this pilot study, we describe the associations identified via a cross-sectional survey among demographic variables, depression, self-efficacy, and glycemic control in a primarily minority population (mean age = 57.9 years; n = 30) with diabetes mellitus. Descriptive, bivariate, and correlation analyses were conducted. A significant inverse relationship was detected between depression and self-efficacy; however the relationship between depression and A1C was not significant. The implications of these findings include the need for interventions that regularly screen for depression and self-efficacy in persons diagnosed with diabetes mellitus, especially in the earlier years of diagnosis.

The relationships between illness and treatment perceptions with adherence to diabetes self-care: A comparison between Arabic-speaking migrants and Caucasian English-speaking patients

AIMS

To compare illness and treatment perceptions between Arabic-speaking immigrants and Caucasian English-speaking people with type 2 diabetes, and explore the relationships between these beliefs and adherence to self-care activities.

METHODS

A cross-sectional study was conducted in healthcare settings with large Arabic populations in metropolitan and rural Victoria, Australia. Adherence to self-care activities, illness and treatment perceptions, and clinical data were recorded. Bivariate associations for continuous normally distributed variables were tested with Pearson's correlation. Non-parametric data were tested using Spearman's rank correlation coefficient.

RESULTS

701 participants were recruited; 392 Arabic-speaking participants (ASPs) and 309 English-speaking participants (ESPs). There were significant relationships between participants' illness and treatment perceptions and adherence to diabetes self-care activities. ASPs' negative beliefs about diabetes were strongly and significantly correlated with poorer adherence to diet recommendations, exercise, blood glucose testing and foot care. ASPs were significantly less adherent to all aspects of diabetes self-care compared with ESPs: dietary behaviours (P=<0.01; 95% confidence interval (CI)=-1.17, -0.84), exercise and physical activity (P=<0.001, 95% CI -1.14, -0.61), blood glucose testing (P=<0.001) and foot-care (P=<0.001). 52.8% of ASPs were sceptical about prescribed diabetes treatment compared with only 11.2% of the ESPs. 88.3% of ASPs were non-adherent to prescribed medication, compared with 45.1% of ESPs.

CONCLUSIONS

Arabic-speaking migrants' illness and treatment perceptions were significantly different from the English-speaking group. There is a pressing need to develop new innovative interventions that deliver much-needed improvements in adherence to self-care activities and key health outcomes.

Depressive symptoms prior to and following insulin initiation in patients with type 2 diabetes mellitus: Prevalence, risk factors and effect on physician resource utilisation

AIMS

To study the frequency and intensity of depressive symptoms and associations with physician resource utilisation following insulin initiation in patients with type 2 diabetes mellitus.

METHODS

SOLVE was a 24-week observational study. In this sub-analysis of data from Poland, depressive symptoms were evaluated using the Patient Health Questionnaire (PHQ)-9.

RESULTS

PHQ-9 was completed by 942 of 1169 patients (80.6%) at baseline, and 751 (64.2%) at both baseline and final (24-week) visit. PHQ-9 scores indicated depressive symptoms in 45.6% (n=430) at baseline, and 27.2% (n=223) at final visit. Mean PHQ-9 change was -2.38 [95% CI -2.73, -2.02], p<0.001. Depressive symptoms at baseline (OR 6.32, p<0.001), microvascular disease (OR 2.45, p=0.016), number of physician contacts (OR 1.16, p=0.009), and change in HbA1c (OR 0.60, p=0.025) were independently associated with moderate/severe depressive symptoms at final visit. Patients with more severe depressive symptoms spent more time training to self-inject (p=0.0016), self-adjust (p=0.0023) and manage other aspects of insulin delivery (p<0.0001). Patients with persistent depressive symptoms had more telephone contacts and dose changes at final visit than those without (both p<0.05).

CONCLUSIONS

Depressive symptoms are common with type 2 diabetes and associated with increased healthcare utilisation, reinforcing the need for holistic interdisciplinary management approaches.

Incorporating Psychological Predictors of Treatment Response into Health Economic Simulation Models: A Case Study in Type 1 Diabetes

BACKGROUND

. Health economic modeling has paid limited attention to the effects that patients' psychological characteristics have on the effectiveness of treatments. This case study tests 1) the feasibility of incorporating psychological prediction models of treatment response within an economic model of type 1 diabetes, 2) the potential value of providing treatment to a subgroup of patients, and 3) the cost-effectiveness of providing treatment to a subgroup of responders defined using 5 different algorithms.

METHODS

. Multiple linear regressions were used to investigate relationships between patients' psychological characteristics and treatment effectiveness. Two psychological prediction models were integrated with a patient-level simulation model of type 1 diabetes. Expected value of individualized care analysis was undertaken. Five different algorithms were used to provide treatment to a subgroup of predicted responders. A cost-effectiveness analysis compared using the algorithms to providing treatment to all patients.

RESULTS

. The psychological prediction models had low predictive power for treatment effectiveness. Expected value of individualized care results suggested that targeting education at responders could be of value. The cost-effectiveness analysis suggested, for all 5 algorithms, that providing structured education to a subgroup of predicted responders would not be cost-effective.

LIMITATIONS

. The psychological prediction models tested did not have sufficient predictive power to make targeting treatment cost-effective. The psychological prediction models are simple linear models of psychological behavior. Collection of data on additional covariates could potentially increase statistical power.

CONCLUSIONS

. By collecting data on psychological variables before an intervention, we can construct predictive models of treatment response to interventions. These predictive models can be incorporated into health economic models to investigate more complex service delivery and reimbursement strategies.

Distress and type 2 diabetes-treatment adherence: A mediating role for perceived control

OBJECTIVE

To better understand independent pathways linking emotional distress, medication adherence, and glycemic control in adults with Type 2 diabetes, as well as the potential mediating effects of perceived control over illness and self-efficacy.

METHOD

Adults with Type 2 diabetes (N = 142) were recruited for an intervention study evaluating cognitive-behavioral therapy for adherence and depression. Depressive symptom severity was assessed via semistructured interview. Validated self-reports assessed diabetes-related distress, perceived control over diabetes (perceived control), self-efficacy for diabetes self-management, and medication adherence. Glycemic control was evaluated by hemoglobin A1C. Only baseline data were included in correlational and linear regression analyses.

RESULTS

Perceived control was an important mediator of emotional distress for both medication adherence and A1C outcomes. Specifically, regression analyses demonstrated that diabetes distress, but not depression severity, was significantly related to medication adherence and A1C. Self-efficacy and perceived control were also independently associated with medication adherence and A1C. Mediation analyses demonstrated a significant indirect effect for diabetes distress and medication adherence through perceived control and self-efficacy. The relationship between distress and A1C was accounted for by an indirect effect through perceived control.

CONCLUSION

Results demonstrated that diabetes-related emotional distress is associated with poorer treatment adherence and glycemic control among adults with Type 2 diabetes; these relationships were partially mediated through perceived control over diabetes. Perceptions of one's personal ability to influence the course of diabetes may be important in understanding the pathway between emotional distress and poor diabetes-treatment outcomes.

The Relationship between Cognitive Appraisal and Adherence to Medical Regimens in Type 2 Diabetic Patients

INTRODUCTION

Non-adherence to medical regimen has remained a challenge to the medical profession as well as to social sciences. To achieve positive results, the factors negatively impacting patient adherence to medical regimens (i.e., diet, drug and exercise regimen) must be scrutinized in detail. The objective of this research was to explore the relationship between cognitive appraisal and adherence to medical regimens in type 2 diabetic patients.

METHODS

In this correlational study, 218 type 2 diabetes patients receiving treatment at the Diabetes Clinic affiliated with Gonabad University of Medical Sciences were selected through non-probability (convenience) sampling from April 2012 to May 2013. Two valid and reliable questionnaires of cognitive appraisal and adherence to medical regimens were completed by each patient. The data were analyzed using SPSS ver 13.

RESULTS

A relationship was observed between perceived cognitive and adherence to some aspects of medical regimen. Also direct relationship was observedbetween perceived cognitive in form challenge and adherence of diet in patients with diabetes. There was no statistically significant relationship between aspects of cognitive appraisal and adherence to the drug regimen.

CONCLUSION

The results suggest that interventions undertaken to improve adherence to medical regimen, particularly to drug regimen in patients with type 2 diabetes, should be focused on enriching cognitive appraisal. Nurses need to help patients perceive diabetes as less of a threat and in fact should empower them, so as to look upon it as more of a challenge.

Analysis of some predictive factors of quality of life among type 2 diabetic patients

INTRODUCTION

Considering the chronic nature of diabetes and its significant effect on quality of life of patients, the present study was conducted to evaluate predictors of quality of life in these patients in order to facilitate planning health promotion intervention programs.

MATERIALS AND METHODS

The present study was designed as a cross-sectional study on 140 type 2 diabetic patients of Om-ol-Banin Diabetes Center of Isfahan. Data collection tool was a multidimensional questionnaire including demographic and disease related data (12 items), the standard scale for diabetes distress (17 items), the standard scale for self-efficacy in diabetic patients (8 items), and standard scale for specific quality of life of diabetic patients (15 items). Collected data were evaluated by SPSS version 11.5 using the Chi-square test, Independent T-test, ANOVA, Pearson correlation and multivariate regression analysis.

RESULTS

Results showed that the quality of life of diabetic patients had a statistically significant correlation with diabetes distress variable (P < 0.001) and self-efficacy variable (P < 0.001). In this study R(2) (predictive power) was 0.66. Multivariate regression model indicated diabetes distress (β = -0.277, P = 0.01) and self-efficacy (β = -0.161, P < 0.001) as variables influencing adjusted self-management for other variables.

CONCLUSION

The result of the present study urges that in planning health promotion interventions in the field of diabetes, more attention be paid to self-efficacy and diabetes distress variables in order to improve the efficiency and effectiveness of the interventions carried out.

Diabetes connect: African American men's preferences for a community-based diabetes management program

PURPOSE

The purpose of the study is to explore African American men's perceptions of how community-based, community-health worker (CHW)-delivered diabetes interventions might best be implemented.

METHODS

Four 90-minute focus groups were guided by a trained moderator with a written guide to facilitate discussion on the topic of diabetes management and preferences for community-based programs. Participants were recruited from the diabetes education database at a safety-net health system in Jefferson County, AL. Two independent reviewers performed content analysis to identify major themes using an iterative, combined deductive and inductive approach.

RESULTS

There were 25 male participants. Mean years living with diabetes was 9.6 (range, 1-20). Participants demonstrated knowledge of self-management strategies and identified various hardships including emotional and physical manifestations of diabetes, dietary restrictions, and institutional frustrations with the health system that contributed to self-management barriers. Their preferred CHW responsibilities were to educate, hold support groups, help track daily activities, and help find resources. Potential concerns included the need for confidentiality and fears of being stereotyped.

CONCLUSIONS

Participants identified critical self-management strategies but endure hardships that present barriers to daily diabetes management. Preferences for community-based programs and suggested CHW responsibilities could help to overcome many of those barriers by increasing access and providing support.

Long-term outcomes from Healthy Eating and Exercise Lifestyle Program for overweight people with heart disease and diabetes

BACKGROUND

The benefits of exercise and weight reduction for overweight or obese people with coronary heart disease and/or diabetes mellitus are well recognised. The Healthy Eating and Exercise Lifestyle Program demonstrated these outcomes at 4 months, but longer-term outcomes are not yet reported.

AIM

To determine whether positive weight, body mass index, waist and exercise duration outcomes were sustained in the long term (12 months) and to identify the independent predictors of these outcomes at 4 and 12 months.

METHODS

Longitudinal design, combining data of all Healthy Eating and Exercise Lifestyle Program participants (intervention and wait-list control, n = 134). Participants had a body mass index between 27 and 39 kg/m(2) and had completed cardiac rehabilitation and/or diabetes education programmes. Healthy Eating and Exercise Lifestyle Program intervention included an active phase of two 1-hour group-based supervised structured exercise sessions every week for 4 months and four 90-minute group information and support sessions. The maintenance phase included one 90-minute group-based booster information session and three 15-minute goal-focused telephone follow-up calls over 8 months.

RESULTS

Participants had statistically significant reductions from baseline in weight, body mass index and waist circumference and improvements in exercise duration and capacity at 4 and 12 months. Time, self-efficacy, depressive symptoms and male gender were independent predictors for body mass index, waist and/or exercise duration (p < 0.05).

CONCLUSION

The Healthy Eating and Exercise Lifestyle Program was an effective programme to achieve and sustain weight loss and increase exercise participation over 1 year.

Medication beliefs mediate between depressive symptoms and medication adherence in cystic fibrosis

OBJECTIVE

Depression is a known barrier to regimen adherence for chronic conditions. Despite elevated depression rates and complex regimens for people with cystic fibrosis (CF), little is known about associations between depressive symptoms and CF adherence. One possibility is that depressive symptoms distort beliefs about medications, which may influence adherence.

METHOD

Adolescents and adults (N = 128; mean age = 29 ± 11 years, range = 16-63, 93% Caucasian) with CF reported on depressive symptoms and medication beliefs (self-efficacy, motivation, perceived importance, and outcome expectancies related to taking medications). Medication adherence was assessed objectively through pharmacy refill data. Cross-sectional structural equation models evaluated medication beliefs as a mediator between depressive symptoms and medication adherence.

RESULTS

Twenty-three percent of participants exceeded clinical cutoffs for depressive symptoms. Participants took less than half of prescribed pulmonary medications (mean adherence rate = 44.4 ± 26.7%). Depressive symptoms were correlated with adherence (r = -.22, p < .05), and medication beliefs (b = -0.13, 95% CI [-0.24, -0.03]) significantly mediated this relation. Higher depressive symptoms were associated with less positive medication beliefs (b = -0.27, p < .01), which were associated with lower medication adherence (b = 0.49, p < .01).

CONCLUSIONS

Depressive symptoms are related to beliefs about and adherence to CF medications. Monitoring depressive symptoms and medication beliefs in routine CF care may help identify risks for nonadherence and facilitate interventions to reduce depression, adaptive medication beliefs, and ultimately improve adherence and CF management.

Factors associated with diabetes-related distress: implications for diabetes self-management

As 7.8% of the U.S. population is affected by diabetes, health care providers are tasked with providing resources to assist patients toward self-management. Psychosocial issues have an effect on diabetes self-care. Diabetes-related distress is associated with self-management and lower A1C. This cross-sectional study seeks to understand how demographic factors, psychological orientations, support, and diabetes management behaviors predict diabetes-related distress. This study uses data from 267 adults with Type 2 diabetes. The Diabetes Distress Scale (DDS) is a 17-item scale measuring diabetes-related distress including emotional distress, physician-related distress, regimen distress, and interpersonal distress. Hierarchical regression was conducted in four stages. The final model explains 48% of the variance in DDS. Significant factors related to lower DDS were older age, lower body mass index, higher self-efficacy, higher levels of health care provider support, and a healthy diet. Findings of this study help health care providers know where to focus to reduce diabetes-related distress. Health care provider support is significant in reducing DDS. Diabetes education may want to include strategies that increase self-efficacy and assist people with diabetes to obtain a healthy weight through a more healthful diet.

Effect of diabetes self-efficacy on glycemic control, medication adherence, self-care behaviors, and quality of life in a predominantly low-income, minority population

OBJECTIVE

This study examined the effect of self-efficacy on glycemic control, self-care behaviors, and quality of life in low-income, minority adults with diabetes.

METHODS

Data on 378 participants were examined. Multiple linear regression assessed associations between self-efficacy, hemoglobin A1c, medication adherence, diabetes knowledge, self-care behaviors and quality of life.

RESULTS

Self-efficacy had modest correlations with glycemic control (r = -.250, P < .001), medication adherence (r = -.352, P < .001), diabetes knowledge (r = .118, P = .039), diet (r = .420, P < .001), exercise (r = .220, P < .001), blood sugar testing (r = .213, P < .001), foot care (r = .121, P = .032), and mental health related quality of life (r = .137, P = .017). In the regression model, self-efficacy was significantly associated with glycemic control (3 = -.104, 95% CI: -.157, -.051), medication adherence (3 = -.067, 95% CI: -.090, -.044), diet (3 = .150, 95% CI: .108, .191), exercise (-3 = 113, 95% CI: .065, .161), blood sugar testing (3 = .107, 95% CI: .049, .164) and mental health related quality of life (3 = .112, 95% CI: .051, .173).

CONCLUSION

Higher self-efficacy was associated with improved glycemic control, medication adherence, self-care behavior and mental health related quality of life.

PRACTICE IMPLICATIONS

Emphasis on self-efficacy is relevant for educational interventions developed for low-income, minority populations.

Association of HbA1c with emotion regulation, intolerance of uncertainty, and purpose in life in type 2 diabetes mellitus

BACKGROUND

The extant literature lacks breadth on psychological variables associated with health outcome for type 2 diabetes mellitus (T2DM). This investigation extends the scope of psychological information by reporting on previously unpublished factors.

OBJECTIVE

To investigate if intolerance of uncertainty, emotion regulation, or purpose in life differentiate T2DM adults with sustained high HbA(1c) (HH) vs. sustained acceptable HbA(1c) (AH).

SUBJECTS AND METHODS

Cross-sectional observational study. Adult patients with diagnosed T2DM meeting inclusionary criteria for AH, HH, or a nondiabetic reference group (NDR) were randomly selected and invited to participate. Patients who consented and participated resulted in a final sample of 312 subgrouped as follows: HH (n = 108); AH (n = 98); and NDR (n = 106). Data sources included a survey, self-report questionnaires, and electronic medical record (EMR).

RESULTS

HH individuals with T2DM reported lower purpose in life satisfaction (p = 0.005) compared to the NDR group. The effect size for this finding is in the small-to-medium range using Cohen's guidelines for estimating clinical relevance. The HH-AH comparison on purpose in life was nonsignificant. The emotion regulation and intolerance of uncertainty comparisons across the three groups were not significant.

CONCLUSIONS

The present study determined that lower purpose in life satisfaction is associated with higher HbA(1c). In a T2DM patient with sustained high HbA(1c), the primary care clinician is encouraged to consider screening for purpose in life satisfaction by asking a single question such as "Do the things you do in your life seem important and worthwhile?" The patient's response will assist the clinician in determining if meaning or purpose in life distress may be interferring with diabetes self-care. If this is the case, the clinician can shift the conversation to the value of behavioral and emotional health counseling.

Employment Outcomes in Persons With Diabetes

Low health literacy is common among adults and is related to adverse health outcomes. It also impacts health management and one’s ability to control his or her chronic illness. The current study examined the association of health literacy and diabetes management self-efficacy with employment among 126 individuals with diabetes. No relationship was found between health literacy and employment. Diabetes-management self-efficacy was not directly related to employment but it was indirectly linked to it through physical health and lack of interference of diabetes with activities of daily living. This research suggests that strategies to improve self-efficacy may contribute to improved health and employment outcomes. Implications for rehabilitation counseling practice and research are discussed.
